I have been using the Sony Emount cameras since I picked up a NEX3 several years ago. quickly purchased the 16-70 when it came available, and LOVE it. Have the 18-55, and it works well. So when I went to get the a6000 I figured I would just get the body, but the body wasn't available. So I picked it up with the 16-50 and it is a fun little lens. Wow distortion in the few photos I have taken, but easily corrected so that sholdn't be a problem. But it is so cute, and small and light I figure it will just stay on the camera. Would I trade it for the 16-70, No. Am I glad I purchased with the lens, Yeah. Would I purchase without the body, No.

So My take is, Get it with the kit lens. If it is enough, great. If not spring for the 16-70 or the 18-105 depending on the work you do. But I bet you want to keep it and not get rid of it at the end of the day, It is just so Cute! and it does work well.
